Free Measurements 02 Practice Test - 5th Grade
Question 1
Select the option in which the measurement conversion is correct.
1 m = 100 mm
1 km = 100 m
1 m = 100 cm
1 cm = 100 mm
SOLUTION
Solution : C
We know that,
1 m = 100 cm
1 km = 1000 m
1 cm = 10 mm
∴ In the 4 given options, 1 m = 100 cm is correct.
Question 2
1 L =
10 mL
100 mL
1000 mL
10000 mL
SOLUTION
Solution : C
When we convert a larger unit (L) to a smaller unit (mL), we multiply by the conversion factor.
Hence, 1 L = 1×1000 = 1000 mL
Question 3
The milk in a spoon is approximately
5 mm
5 cm
5 mL
5 L
SOLUTION
Solution : C
We know that spoon is a small object which can hold very little quantity of liquid.
Here, millimetre (mm) and centimetre (cm) are the units of length.
A litre is used to measure a large quantity of liquid.
Therefore, milk in a spoon is approximately 5 mL.
Question 4
Long distances between two places are measured in _____.
Millimetre
Milligram
Kilometre
Kilogram
SOLUTION
Solution : C
Kilogram (kg) and milligram (mg) are the units of mass.
Millimetre (mm) is the unit used to measure the length of very small objects like the length of a pin, seed etc.
Kilometre (km) is the unit used to measure long distances between two places.
Question 5
By how much is the length of string A more than string B?
10 mm
20 mm
30 mm
40 mm
SOLUTION
Solution : A
String `A` is starting from 1 cm.
∴ Subtract 1 cm from 9 cm.
Lenght of string A
=9 cm−1 cm=8 cm
String `B` is starting from 3 cm.
∴ Subtract 3 cm from 10 cm.
Length of string B
=10 cm−3 cm=7 cm
Thus, the difference in length of String `A` and String `B`
=8 cm−7 cm=1 cm=10 mm
∴ The length of string A is more than string B by 10 mm.
Question 6
Find the missing quantity:
1 L = 350 mL +
600
650
700
750
SOLUTION
Solution : B
We know that,
1 Litre = 1000 mL
We already have 350 mL,
⇒ 1000 mL - 350 mL = 650 mL
∴ 1000 mL = 350 mL + 650 mL
Question 7
8 hectometres =_______ metres.
8
80
800
8000
SOLUTION
Solution : C
When we convert a larger unit (hectometre) to a smaller unit (metres) we multiply by the conversion factor.
1 hectometre = 100 mHence 8 hectometres = 8 × 100 = 800 m
Question 8
Tina went to a shop to buy 3 litres of orange juice for a party. The store sold orange juice only in 250 mL cartons. How many 250 mL cartons will Tina need to buy?
4
8
16
12
SOLUTION
Solution : D
1 L=1000 mL
⇒3 L=3×1000 mL
=3000 mL
Therefore, the quantity of juice Tina wants to buy equals 3000 mL.
Since the store sells only 250 mL cartons, the number of such cartons that Tina has to buy is given by 3000250=12.
Question 9
An ant goes 3 cm forward then goes 2 cm backwards and then finally 5 cm forward. What is the final position of the ant if the initial position of the ant is shown on the scale?
6 cm
7 cm
8 cm
9 cm
SOLUTION
Solution : C
Initial position of the ant = 2 cm
Ant goes 3 cm forward = 2 cm + 3 cm = 5 cm
Ant goes 2 cm backward = 5 cm - 2 cm = 3 cm
Finally, the ant goes 5 cm forward = 3 cm + 5 cm = 8 cm
∴ The final position of the ant is 8 cm
Question 10
From the given figure, find the weight of the mangoes.
2 kg
2.4 kg
2.8 kg
3 kg
SOLUTION
Solution : B
Weight of mangoes + 100 g + 500 g = 1 kg + 2 kg
⇒Required weight + 600 g =3 kg
⇒Required weight=3 kg - 600 g
To move ahead, we need to convert the units. Since we need the final answer in kilograms, let us convert 600 g to kilograms.
1 kg=1000 g
⇒ 600 g=6001000 kg
=0.6 kg
∴ Weight of mangoes =3 kg - 0.6 kg
=2.4 kg
